Stockton-based In-Shape hopes to convert the 31,000-square-foot supermarket into a full-service health club, including an indoor pool and spa, racquetball court, kids club and group exercise area, and cycling studios. But the plan is still under city review.

"We have applied for a use permit, and there is a hearing scheduled for January," Clark said Tuesday.

Centro-Mart Inc. opened Apple Marketplace in late 1999 and continues to operate the grocery. It took over the space from the short-lived Landucci's Marketplace. Prior to that, it had been a Sell-Rite market.

Centro-Mart President and Chief Executive Mel Young declined Tuesday to comment on the reported conversion plan.

A year ago, Stockton-based Centro-Mart ended a 65-year history when it closed all four of its stores in Stockton, which have since been leased to and reopened as Dollar General outlets.

Clark said there has long been a demand for In-Shape to establish a facility in Lodi.

"We have quite a few members who live in Lodi," she said. "It all comes down to getting the right spot, getting the right building to do it."

In-Shape, founded in 1981 in Stockton, is growing rapidly.

In mid-2009, when the company agreed to become the anchor tenant in the former Pacific State Bank tower in downtown Stockton, it had 34 locations in Northern California from Sacramento to Bakersfield and out to the coast. Today, it has 62 health clubs in the region, Clark said, with more to come in 2013.
